AMT 7: New Instrumentation
9:00am - 9:15am
Quantifying the consistency of number size distributions in the size range from 1-55 nm
1GRIMM Aerosol Technik, Germany; 2German Meteorological Agency, Germany; 3Airmodus, Finland
Here, we present results of a 1-month field measurement campaign carried out at the Hohenpeissenberg Observatory of the German Meteorological Agency (DWD). The used instruments comprise the novel GRIMM PSMPS nano mobility particle size spectrometer and a TROPOS type SMPS. The aim of this study is to gather data for an instrument intercomparison and an analysis of the overlapping region of the MPSS system since it is of special interest how well the recorded size spectra of the individual setups match in their overlapping size region of 10-55nm.
9:15am - 9:30am
Harmonization of UFP Measurements: Characterization and Application of a Novel Wide- Range SMPS
1TSI GmbH, Neuköllner Strasse 4, 52068 Aachen, Germany; 2TSI Incorporated, 500 Cardigan Road, Shoreview, Minnesota 55126, USA; 3TSI France Inc., Hôtel Technologique BP100, Technopôle de Chateau Gombert, Marseille, 13382, France
Characterization and continuous monitoring of ambient ultrafine particles (UFP) has been a topic in aerosol research for the last three decades. With much experience gained during this time, the next important step is harmonizing these measurements on the European level. This study will introduce a newly developed wide-range Scanning Mobility Particle Sizer (model 3938W50, TSI Inc., USA). We will present first results from calibration measurements and an instrument comparison with atmospheric aerosol following the recommendations given in the CEN technical specifications, documenting full conformity with CEN/TS 17434.
9:30am - 9:45am
Concept, first testing and validation of a new polar nephelometer
1Paul Scherrer Institute, Laboratory of Atmospheric Chemistry, Villigen, Switzerland; 2Micos Engineering GmbH, Dübendorf, Switzerland
The polarized light scattering phase function of an aerosol, i.e. the angular, spectral and polarization dependence of scattered light for given incident radiation, is of central importance. For example, aerosol remote sensing methods often rely on polarimetry, as aerosol physical and optical material properties can be retrieved from such data by solving the inverse problem. Here we present a new in-situ instrument based on the imaging polar nephelometry approach, which makes measurements of the polarized light scattering phase function with high angular resolution possible.
9:45am - 10:00am
Newly developed instrumentation for measuring highly oxygenated organic molecules at atmospheric pressure
1Laboratory of Environmental Physics, Institute of Physics, University of Tartu, Tartu, 50411, Estonia; 2Airel Ltd., Tõravere, 61602, Estonia
We will introduce a novel instrument for measuring total concentration of highly oxygenated organic molecules. Some technical details are mentioned within the abstract and a lab experimental results are shown.
